Nothocrax urumutum

NOTES

The habitat suitability model generated in Maxent showed extensively areas that are suitable in climatic terms for this species in almost all tropical Colombia. Areas west of the Andes are not known to be occupied by this curassow and were excluded from its potential distribution map. Additionally, there is a vast area in the Orinoco region predicted by our model as marginally suitable, from where there are no records at all and which is suspected this species does not occupy. Similarly, this area was not included in our final potential distribution map but was highlighted separately.

Assuming that the distribution of the species may have filled the complete climatic model generated in the Colombian Amazon, its potential distribution today in remnants of forest is about 474,452 km², which corresponds to a loss of 9 % of its potential original distribution in the region due to deforestation.
